ELECTRIC LAMP,

Application flied August 28, 1922. Serial No. 583,857.

To all whom it may concern:

Be it known that I, CLARENCE Lmnn, a. citizen of the United States,residing at Philadelphia, in the count of Philadelphia and State ofPennsylvania, ave invented new and useful Im rovements in ElectricLamps, of which the ollowing is a specification.

This invention relates to electric lamps and particularly to those runfrom a dry battery mounted within the framework or shell of the lamp,and one of the principal objects of the invention is -to producev adevice of this nature in which when the lamp is picked up the contact isautomatically made' for lighting the lamp. v

Another object of this invention is to produce a device of thischaracter in which the lamp may be locked in either its operative orinoperative position.

Another object of the invention is to produce a device of this nature ofa pleasing and artistic design and yet containing all the necessaryelements of such a lampand covering and concealing the same.

Another object is to produce a. device of this nature which should besimple of construction, cheap to manufacture, and highly eiiicient forthe purpose for which it is designed. I

With these and other objects in view as will be more apparent as thespecification proceeds, the invention resides in certain novelconstruction and combination and arrangement of parts, the essentialfeatures of which are hereinafter fully described, are particularlypointed out in the appended claim, and are illustrated in theaccompanying drawing in which:

Figure 1 is an elevation view of my improved electric lamp.

Figure 2 is a vertical sectional view of the same.

Figure 3 is a bottom plan view of the same.

Like characters of reference. refer to like parts in all the views.

Referring to the drawing in detail, 10 represents a base which may be ofwood, metal, or any suitable material, and which is hollowed out at 11to provide an aperture for receiving the battery 12 which has the usualcontact members 13 and 14. It will be understood that if the base 10 ismade of metal, the a erture may be lined with any suitable in'su ationto prevent short circuiting of the battery.

. The bottom of the base is provided with a disc 15 which closes thebottom of the aperture 11 and is provided with cut-away ortions 16 whichco act with legs 17 to old the member 15 in closed position to maintainthe battery in place; As shown the legs are in the forms of ballsprovided with threaded extensions which are screwed into the base 10 andoverlie the plate 15, although it is to be understood that any suitableform of leg may be used.

Secured to the base 10 and rising therefrom is a metallic tube 18 andfast to the tube is a wire 19 carrying a contact grip 20 which isadapted to'receive and grasp the contact member 14 of the battery.

The contact member 13 receives a similar grip 21 to which is attachedone end of a wire 22 covered with a coating of insulation and passing upthrough the tube 18 to a point near its top where the tube is providedwith diametrically disposed slots 23. Passing through these slots is aninsulating member 24 which carries a contact plunger or rod 25, thelower end of which is connected to the wire 22. The rod 25 is held fromcontacting with the sides of the tube 18 by the aforementionedinsulation member 24.. The upper end of the tube 18" is internallythreaded to receive an electric light bulb 26. A flange 27 is secured tothe tube 18 above-tho member 24 and a camouflaged candle28 is held inplace between the flan e 27 and the bulb 26.

Tie insulation 24 is provided with ears 29 which extend through theaforesaid slots in member 18 and are secured at their outer ends to theupper end of a hand grip 30 which is slidably mounted on the tube 18.

From the description thus far, it will be obvious that when one layshold on the haudle or grip 30 and raises the device from its restingplace, the member 30 will move upwardly along the tube 18 carrying with.it the-insulating member 24 and contact rod 25 until the latter comesin contact with the llO It will be readily understood that if the knob31 is forced into bindin position while the hand base 30 is in its lowerposition,

then the lamp may be lifted without lighting and that if the knob ismoved into binding position when the hand base 30 is raised, then thelamp will be locked in lighted position.

From the above it will be seen that I have produced a convenient,artistic, and economical lamp in which when it is attempted to lift thelamp from its support, the llght will be automatically turned on. WhileI have described what I deem tobe the most desirable embodiment of myinvention, it is obvious that there are many ways in which a lamp ofthis nature could oe constructed so that the lamp would be turned onupon lifting the lamp, and I therefore do not limit myself to the oneembodiment herein shown nor to anythingless than to the whole of myinvention except as claimed.

What I claim An electric lamp comprising a base, an electric batterytherein, a tube rising from the base and having conductive connectionwith one terminal of said battery, a'lamp bulb carried by the upper endof said tube, a contact plunger sup orted centrall within the tube andinsu ated therefr 111, said contact plunger connected to the otherterminal of the battery, said tube provided -with slots, projectionsconnected to said plunger and projecting through said slots,

a hand grip about a portionof said tube and engaging said projectionsfor moving the contact plunger into circuit closing engage.- ment withthe lamp. 7 y

In testimony whereof I afiix my signature.

CLARENCE LIPPER.
